How to create a patch for a python-for-android recipe

Since it's not documented well I thought I'd do a post on how to create a patch for a python-for-android recipe.

If you have to modify an existing recipe you can get the source package p4a downloads from ~/.local/share/python-for-android/packages/<recipe-name>.

This is typically a tar.gz or zipped source bundle. Extract it and create a copy. Rename the copy to something like "<recipe-name>-patched" or simply "patched".

I'm working with the openssl recipe, so mine looks like this

Now modify the patched source to apply all your fixes as needed. Once done you can create a patch file by going to the directory containing both versions and using the "git diff <original> <patched>" command. Then save it to a file by adding "> fix-some-issue.patch" to the end.

Now copy this patch file into your recipe package and add it to the "patches" list (or call "self.apply_patch('fix-some-issue.patch', arch)" ).

Rerun and p4a will apply the patch to the downloaded recipe before attempting to use build and install it!

If you get any errors related to "could not find the file to patch" make sure that the patch files for "a/" are relative to the recipe build directory where the patches are actually applied (may need modified depending on your git diff command).

Happy coding!

Kivy vs React-Native for building cross platform mobile apps

I've built three apps now using Kivy and one with React-Native, just wanted to share my thoughts on both. Just a warning, I am strongly biased towards python and this is all based on opinion and experience and is thus worth what you pay for it. I don't claim to be an expert in either of these, just have worked with each for several months. If something is incorrect I'd love to hear advice. Kivy Demo of one of the apps Pros: Nice to be able to run natively on the desktop WITHOUT a simulator Python is easy to work with Use (almost) any python library Very easy to create custom widgets Kivy properties and data binding just work. Way nicer than React's "state" / flux / redux whatever you want to call it (stupid?). Native interfaces (pyjnius) and (pyobjc) Runs and feels pretty smooth Cons: Default widget toolkit looks like Android 4.4. Requiring you use your own widgets or a theming kit like KivyMD if styling bothers you Creating dy

Control Systems in Python - Part 1 - Bode and Step Response

I hate matlab with passion, yet sadly, nearly everyone uses it. I'm a fan of Python and open source stuff so here's a simple article on how to do some common control systems stuff in Python. First we need to make sure the environment is setup. Install IPython (or you can use any other python shell, but a unicode supported shell is preferred) Install python-control (numpy, scipy) Install sympy These should do if your on Ubuntu/debian: sudo apt - get install python - sympy python-numpy python-scipy python-matplotlib ipython Then you need to install python control, see How to download and install python-control Intro to using Sympy Open ipython and run the following: import sympy from sympy import * sympy.init_printing() s = Symbol('s') Now we can do things like define transfer functions using the symbolic variable s. We can expand the bottom using the .simplify() method and we can do something more complex like... which is really nice because it

Control Systems in Python - Part 2 - Routh Hurwitz

In my last post Control Systems in Python Part 1 , i described how to setup and use Python for doing some basic plotting of transfer functions. One of the biggest benefits of using sympy vs numeric packages like matlab/numpy/scipy is the fact that you can use symbolic variables. This post includes a function for computing the Routh Hurwitz table (Note: It does not work for row's of zeros). Lets do my control systems design homework problem together :) (Warning: I have not verified if this answer is right so please correct me if it’s not!) The Problem The problem is DP 9.11 from Dorf & Bishop’s Modern Control Systems. ISBN 0136024580. Basically we have to design a controller to compensate for a system with a time delay. The controller is: And the system is: First we approximate the exponential term with a 2nd order polynomial using pade(0.4,2) such that: Thus the approximated system is: Using frequency response methods, design the controller so that th
